# Command Line OpenD

# Step 1: Download

download-page

# Step 2: Decompression

  • Extract the file downloaded in the previous step and find the OpenD configuration file OpenD.xml and the program packaged data file Appdata.dat in the folder.
    • OpenD.xml is used to configure the startup parameters of the OpenD program. If it does not exist, the program cannot start correctly.
    • Appdata.dat is a large amount of data information the program needs to use, packaging data to reduce the time of downloading data while starting OpenD. If it does not exist, the program can not start correctly.
  • Command line OpenD supports user-defined file paths, refer to Command line startup parameters

# Step 3: Parameter Configuration

  • Open and edit the configuration file OpenD.xml as the picture below. For general use, you only need to change your account and login password, and other options can be modified according to the instructions in the following table.

Tips

  • To ensure safety of your trading accounts, if the listening address is not local, you must configure a private key to use the trading interface. The quote interface is not subject to this restriction.

  • When the WebSocket listening address is not local, you need to configure SSL to start it, and a password should not be set during the certificate private key generation.

  • Ciphertext is represented in hexadecimal after plaintext is encrypted by 32-bit MD5, which can be calculated by searching online MD5 encryption (note that there may be a risk of records colliding with libraries calculated through third-party websites) or by downloading MD5 computing tools. The 32-bit MD5 ciphertext is shown in the red box area (e10adc3949ba59abbe56e057f20f883e):

  • OpenD reads OpenD.xml in the same directory by default. On MacOS, due to the system protection mechanism, OpenD.app will be assigned a random path at run time, so that the original path can not be found. At this point, there are the following methods:

    • Execute fixrun.sh under tar package
    • Specify the configuration file path with the command line parameter -cfg_file, as described below
  • The log level defaults to the info level. During the system development phase, it is not recommended to close the log or modify the log to the warning, error, fatal level to prevent failure to locate problems.

# Step 4: Command Line Startup

  • On the command line, change the directory to the folder which OpenD is located, and run the following command to start Command Line OpenD with configuration from OpenD.xml.
    • Windows:OpenD
    • Linux:./OpenD
    • MacOS:./OpenD.app/Contents/MacOS/OpenD
Command Line Startup Parameters
  • You can also start with parameters on the command line, some of which are the same as the OpenD.xml configuration file. Parameter format: -key=value startup-command-param.png
    For example:

    • Windows:OpenD.exe -login_account=100000 -login_pwd=123456 -lang=en
    • Linux:OpenD -login_account=100000 -login_pwd=123456 -lang=en
    • MacOS:./OpenD.app/Contents/MacOS/OpenD -login_account=100000 -login_pwd=123456 -lang=en
  • If the same parameters exist on both the command line and the configuration file, the command line parameters take precedence. For details of the parameters, please see the following table:

  • parameter list:

    Configuration Item Description
    login_account Login account.
    login_pwd Plaintext of login password.
    login_pwd_md5 Login password ciphertext (32-bit MD5 encrypted hexadecimal).
